UNITED STATES PATENT OFFICE.

GEORGE \V. HOWELL, OF GOVINGTON, KENTUCKY.

DOOR.

SPECIFICATION forming part of Letters Patent No. 255,788, dated April 4, 1882.

Application filed October 1, 1881.

To all whom it may concern:

Be it known that I, GEORGE W. HOWELL, of Govington, Kenton county, Kentucky, have invented certain new and useful Improvements in Doors, of which the following is a specification, reference being bad to the accompanying drawings, in which- Figure 1 is a perspective view of a section of sidewalk having two openings fitted with my improved doors; Fig. 2, a vertical section of a frame with double door,- and Fig. 3 a section of building-wall with a portion of contiguons door-frame.

This invention pertains to sidewalk cellardoors or other horizontal doors similarly located with reference to a building; andit relates to the construction and relation of parts, as hereinafter set forth.

In Fig. 1, A A represent two door-frames set at the cellar-way in a sidewalk. Theleft-hand doors are closed and lie neatly flush with the sidewalk, no hinges protruding above their upper surface. The right-hand pair of doors are shown in their open position, a portion of each door standing as a vertical guard on the sides of the opening. A is the door-frame. O and B are the doors, and F the point of pivoting. This point is locatedbelow the level of the upper surface of the frame and door, and about an equal distance from the inside edge of the frame, as clearly shown in Fig. 2. The low location of the pivot permits the upper surface to be free from obstructions, and its peculiar location with reference to the said upper and side frame permits the door, when open, to occupy the vertical guard position shown. The location of the pivot some distance from the frame line causes the door in a degree to be balanced upon its pivots, so that downward pressure upon the side nearest the side frame will tend to open the door. A stubborn door may thus be stamped upon with the boot-heel.

' The balancing of the door upon its pivots is further effected by the weightsK, attached to the door opposite the heaviest side. In the drawings the door is formed of sheet metal, secured to the angle'iron skeleton L. At the ends of the door the rib of the an gle-iron is bent downward, as at M, to form the pivots. The pivot-pins F seat in these bends of the skele- (No model.)

ton and in the end faces of the outer doorframe.

D is a stud projecting from the face of the frame and supporting the doors when closed.

I is a weighted lever pivoted to thedoorskeleton, as shown. It carries the latch-hook H, formed so as to automatically hook under the stud D when the door is closed, and the jaw J, formed to project from the surface of the door-skeleton when the latch is unhooked.

G is a handle, being above the door, projectingthrough it, and attached to the weight ed lever I.

I E is a boltslidingin the door-frame. When projected it serves to obstruct the projecting movement of the jaw J, and thus looks the latch. This bolt projects through the frame A through the wall N, so as to bring its inner prolongation, 0, inside the building, where it may be operated from the cellar-ceiling or from a trap or lever in the floor over the cellar. There are no springs about the doors orlatchments. When the door is shut down it auto matically latches. Projecting the bolt E locks the latch. After being unlocked the door is opened by means of the handle, which first lifts the weighted latch-lever, and then becomes a draft-handle to the door.

The door may of course be constructed double or single, and while possessing special merit as a horizontal door, is also applicable to many other positions.

The sliding bolt E, as an obstruction to the unlatching motion, may be formed hy an ordinary lock-bolt in case a key-lock be fastened to the door itself.

I claim as my invention- 1. In a sidewalk-doorway, the combination of frame A, skeleton L, plates 0, pivot F, located as set forth, stud D, latchment H, and

handle G, substantially as and for the purpose 4. In a sidewalk-door, the combination of 0 projecting from the side of said wall oppo- I0 door-sheet O, skeleton L, attached to the doorsite the side from which projects the bolt end sheet, as shown, and the pivot-receiving bend E proper, substantially as and for the purpose M, formed by 21111 angular fieptrtureilofta poliset forth. tion of the ske eton from t e oor-s ee su stantially as and for the purpose set forth. l E
